APPARATUS FOR DRYING AND CONDITIONING YARNS, 80C.

SPECFICATION forming part of Letters Patent NO. 710,467', dated October7, 1902. Application filed January 14,1902. Serial No. 89;'767. (N0model.)

To @ZZ whom t pray concern:

Beit known that we, JAMES KEITH, residing at 27 Farringdon avenue, andWILLIAM XVIN- SHTP TWARDLE, residing at 32 Someriield road, FinsburyPark, London, England, citizens of Ithe United Kingdom of Great Britainand Ireland, have invented certain new and useful Drying-Chambers andApparatus for Drying and Conditioning Yarns, Fabrics, and other Goods,(for which application for patent has been madein Great Britain, No.12,389, dated .lune 1S, 1901,) of which the followingr is aspecification.

This invention relates to drying-chambers and apparatus for heating andcirculating air therethrough for the purpose of drying and conditioningyarns, fabrics, and other goods; and it comprises improvements in theconstruction and arrangement of such chambers and apparatus forconveying the goods through the drying-chambers while being acted on bythe circulating airand automatically delivering them, whereby thenecessity for operators entering the heated chambers is obviated.

In the accompanying drawings, which illustrate the invention, Figure lisa vertical longitudinal section of a drying andconditioning chamber andaccessories constructed and arranged in accordance with the invention;and Fig. 2 is a longitudinal section of the same, the section beingtaken on two different planes. Figs. 3 and 4 are detail views at rightangles to each other of part of the conveying-band.

The apparatus hereinafter described is capable of drying andconditioning yarns and the like in hank form; but the means forconveying the goods through the drying-chambers is particularly designedfor holding woven or other fabrics or garments and for sheets of paperor like flat goods to be dried.

The drying-chamber a has vertical sides and a sloping roof Z), nearwhich a circulating-fan c is situated in a vertical Wallf, extendingdownward for a short distance and dividing the upper portionrot' thechamber a into two compartments. Heating apparatus, such as a coil ofsteam orhot-water pipes CZ, is located in proximity to the Vlan cimmediately under the sloping roof l), and another series ot steampipese near the bottom of the chamber in proximity to the fresh-air inlets g.Air is drawn, as shown by the arrows, from one side of the verticalwallf by the fan c and discharged ou rthe other side, the air passingthrough the heating apparatus d to and through between the goods beingdried or conditioned, the air so directed, together with fresh air drawnin, being directed toward the lower heating apparatus e and thenceupward again to the suction side of the fan c. The surplus or moist airis discharged by a ventilator 7L on the sloping roof, an exit-passage t'being provided in the wall of the building for carrying this surplus airto the atmosphere.

The apparatus for conveying the goods to be dried through thedrying-chamber o. consist-s, as shown by the drawings, of endless bandsj, passing around rollers 0, said bands being made up, as shownparticularly at Figs. 8 and 4, of chain-links Zr., preferably of Tshape, the chain-links 7c being formed with or having attached to themcross laths or blocks Z, to which holdingclips 'm are jointed, the underside of the bandj being steadied and guided in side rails n. Theholding-clips m consist of rollers jointed to the blocks, as shown, thearms p of the joint being of such length that when the clips m are in anapproximately horizontal position they rest against the forward side ofthe adjoining block Z. The goods are inserted between the clip m and thevadjoining block Z by pushing the goods against the rollers m, andthereby raising them, the clips on again reaching their normal positionengaging and firmly holding the goods, which in the case of sheets ofpaper or of garments extend transversely of the chamber d, as shown atoc, Fig. 2, from a clip on one bandj to a clip on the adjacent baud j.

For convenience of inserting and deliveringV the goods' the rollers o,around which the chain-links 7o pass, are fitted in proximity to orwithout the end walls of the chamber CZ, so that the goods may be placedinto clips m by the operator, and at the opposite end the goods areautomatically delivered as the chain-links 7s ride around the roller o,owing to each lath or block Z in the turning opera tion moving away fromthe clip m, jointed to the lath or block Z behind, as shown at Fig. l.

IOO

The blocks Z are formed with heels q to prevent the clips m droppingbelow the horizontal position when the blocks Z are passing around therollers o.

The goods are dried by the action of the heated air in their passagethrough the drying-chamber a, and the operator is not under thenecessity of entering the chamber, but merely slips up the goods througha doorway r into the clips fm at the feeding-in end and may at the sametime actuate a hand-wheel n on the spindle of the roller 0 to moveforward the endless bandj, carrying the clips m, theautomatically-delivered goods being periodically removed by a door atthe opposite end.

Having now described the invention, what we claim, and desire to secureby Letters Patent, is-

l. Means fordrying and conditioningyarns fabrics and other goodscomprising in combination a dryingchamber having vertical walls and asloping roof a ventilator in said roof a vertical wall extendingdownward from the sloping roof vand acirculating-fan located in saidvertical wall, heating apparatus situated in proximity to the fresh-airinlets and close to the discharge side of the fan, an endless-bandconveyer passed around rollers for carrying the goods to be driedthrough the heating-chamber said conveyer being composed of blocks orlaths fixed on the links of endless chains, and clips on these blocksadapted to engage and hold the goods and to automatically release themat the discharge end substantially as described.

2. In chambersfor dryingand conditioning yarns fabrics and other goods,a conveyer for carrying the goods through the chamber composed of anendless band of chain-links passing around roller-blocks secured to saidlinks and rollers jointed to said blocks adapted to engage with and holdthe goods while traveling through the chamber and to free the goods atthe discharge end of said chamber substantially as described.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
